Gran Tierra Posts Loss for First Quarter

Gran Tierra Energy Inc. on Tuesday announced its financial results for the quarter ended March 31, 2007.

Total revenue for the quarter was $4.5 million as compared to $1.0 million for same quarter of 2006. Net loss for the quarter amounted to $6.7 million or $(0.07) per share as compared to a net loss of $1.2 million or $(0.03) per share for the comparable quarter of 2006. Included in the first quarter losses are expenses in the amount of $4.1 million in liquidated damages relating to the potential amount payable to stockholders who participated in a 2006 financing whereby the registration statement for the 50 million units sold during the raise had yet to become effective. The registration of these shares became effective May 14, 2007. There was no comparable expense in the first quarter of 2006.

The company reported cash and cash equivalents of $13.3 million at the end of the first quarter of 2007 as compared to $24 million at December 31, 2006. Total working capital reported at the end of the quarter was $7.0 million as compared to $14.3 million at December 31, 2006. Shareholders' equity decreased from approximately $76.2 million at December 31, 2006 to $69.7 million at March 31, 2007. The company reported no outstanding long-term debt.

Oil and condensate production for the quarter ended March 31, 2007 averaged at 1,260 barrels per day, net after royalty. This is up from approximately 1,050 barrels per day for the fourth quarter of 2006 as a result of drilling activity.

The company reports that it has drilled and completed seven wells to date in 2007. The first well, Puesto Climaco-2D in Argentina, was successful and is currently producing oil. The company drilled and completed six exploration wells in Colombia. Four were dry holes: the Laura-1 in the Talora Block, the Caneyes-1 in the Rio Magdalena Block, and the Soyona-1 and Cachapa-1 wells in the Primavera Block. The company's share of capital in three of the dry holes was funded by joint venture partners resulting in no expended capital on those wells by Gran Tierra. The two remaining wells, Juanambu-1 and Costayaco-1 have both encountered oil. Juanambu-1 is currently testing the productivity of the reservoirs and Costayaco-1 will begin testing upon completion of the Juanambu-1 tests.

The company has working interests in 18 exploration and production contracts in three countries--Argentina, Colombia, and Peru—that encompass approximately 6.2 million acres of land. The vast majority of this land is operated by Gran Tierra, bringing its net acreage position to 5.3 million acres. At the end of 2006 the company reported that it had 3.0 million barrels of externally audited proved oil reserves.

Dana Coffield, President and Chief Executive Officer of Gran Tierra Energy, Inc., commented, "As the first quarter numbers reflect, we have continued making the appropriate investments of capital relating to drilling opportunities resulting from the land acquisitions completed throughout 2006. Our drilling programs in both Colombia and Argentina have begun in earnest and we are very pleased with our progress and results to date."
